DRY CLOSET.

SPECIFICATION forming part of Letters Patent No. 408,086, dated July 30, 1889.

Application filed March 13, 1889.

To all whom it may concern:

Be it known that 1, ANDREW M. CoYLE, a citizen of the United States, and a resident of Washington, District of Columbia, have invented new and useful Improvements in Dry Closets, of which the following is a full and exact description, reference being had to the accompanying drawings.

This invention relates to improvements in dry closets, and has for its objects to provide a closet adj ust-able for the needs of the position n which it is placed and that maybe turned into a recess to conceal it while notin use; to provide a lamp for usein the invention which admits of being filled without taking it out of its position and provides means for observing the flame while in use, and to provide means for preventing the flame of the said lamp being extinguished by sudden downward currents in the draft-pipe.

To these ends the invention consists in providing a T connection attached to the receptacle and forming part of the draft-pipe, to which it is pivotally connected, so that the said receptacle may be moved in a circle around the draft-pipe; in providing a lamp to maintain a constant current of air through the draftpipe. which will allow of being replenished with oil without necessitating its being removed from its position, and is provided with a guard fitting the pipe and having a transparent portion by means of which the flame may be examined, andin providing a small outlet into the draft-pipe for the heated air in the lamp.

In the drawings, Figure 1 is a perspective view of the receptacle provided with the illvention. Fig. 2 is a cross-section of the receptacle and draft-pipe. Fig. 3 is a detail view of the lamp and draft-pipe. Fig. 4c is a plan view showing the distribution of the part where the receptacle is concealed in a closet, the door of which is shown as opened. Fig. 5 is a detail view, in section, of the lower end of the draftpipe.

The letter A designates the receptacle for the excrement. This receptacle I form, by preference, of iron,which I galvanize heavily or paint to prevent the acids getting at and eating the iron. In the drawingsI have shown a single vault, in which case it is small and light enough to carry, and, I have provided Serial No. 303,066. (No model.)

for that purpose handles. Fitting on top of this receptacle is the cover B. This cover is provided with the depending flangeB, fitting the shape of the receptacle and making a close joint therewith to prevent any of the odors escaping around the edges, where the effect of the draft would not be greatly felt. In the center is cut the oblong aperture common to closet-stools.

Rigidly attached 'to the cover B is the wooden seat 0, which is provided with an aperture corresponding in shape to that in the cover B. Hinged to the seat at the rear is the lid D, for closing over the aperture in the cover and seat. At the forward edge it is provided with the but-ton or rest E, to keep it slightly raised and form an inlet for air into the receptacle through the aperture when the lid is closed. If this lid were tightly closed, the effect of the draftpipe in the receptacle would be slight, and when the lid was raised the odors would escape through the aperture.

If the draft in the draft-pipe were strong enough to suck the gases out of the receptacle unassisted by a' current of air in the same, it would create a vacuum, which would render it extremely difficult to raise the lid at all. It is to obviate the difficulties above pointed out that I provide the button E, which by raising the lid slightly allows the air from the room in which the receptacle is placed to flow into the body of the receptacle and over the excrement to the draft-pipe, thus forming a current of air, which, while it takes up all odors and directs them to the draft-pipe, by the same forces dries the excrementby extracting all the liquid properties by evaporation. This renders the residue the more easily dealt with, as it may be burned. Further, it diminishes the quantity by its liquid proportion, and the receptacle takes longer to fill than when this feature is omitted.

Extending from the side of the receptacle A at the top is the short pipe F, which is made integral with the receptacle. Fitting over this pipe is the middle arm G of the T connection G. To the ends of the crossarm of the connection are attached the upper and lower sections ll and H. of the draftpipc. The latter of these sections is slightly conical in shape, the larger end screwed to the floor level with the bottom of the receptacle. At this level it spreads out to form the foot H The two sections H and H are connected by the wires H By means of these wires the structure is held more firmly in position without obstructing the passage into the pipe H.

The foot H has upon either side upwardly and inwardly extending flanges to act as guides for the lamp I and to retain it in position, substantially as shown in Fig. 1 of drawings. The lamp I is flat and elongated, having inclined sides, so that the lower edges will extend under the flanges on the foot H The forward end of the lamp is rounded to correspond to the shape of the pipe H, against which it fits. hen the lamp is thus in position, a guard K, which is rigidly mounted on the top, fits firmly against the pipe H and covers an aperture in that part of the pipe cut there to examine the flame of the lamp, which is inside. In this guard is the transparency, which is formed by cutting a circular hole in the guard and covering the same with isin glass or other transparent material. By means of this transparency the flame may be examined without removing the lamp and thereby causing a cessation of the draft in the L, which extends above the junction of the I pipe G and G of the T. By means of this arrangement a sufficient draft is maintained on the flame and a better draft produced in the pipe H by the introduction of the warm air above the pipe G, while avoiding the difficulty above-mentioned. \Vhen now the downward puffs occur, the wind does not enter in the small pipe, as the upward current of heated air is strong and somewhat confined, and in the event of the puffs being of suffieient duration and strength to effect an entrance the volume when it reaches the lamp is so small as to have little or no effect on the flame.

The upper section II of the draft-pipe is, by preference, carried into the chimney,where it delivers the odors, and thence into the open air. If the receptacle is in an Outhouse, the draft-pipe is carried direct through the roof to the open air above.

In many instances I prefer to conceal the receptacle in a closet prepared for it, as shown in Fig. at. In this construction the receptacle A is revolved around the draftpipe H in and out (as shown by dotted lines) of the closet, it turning on the T connection H. This I find a most desirable feature, as I may disguise the closet as a seat by upholstering the top.

The operation of the invention is to cause a draft in the draft-pipe by means of the lamp I, which gets air enough to feed its flame by the leakage around the guard K, which does not fit tight, being only meant to prevent the flame from sudden drafts, which might blow it out. The draft in the draftpipe creates a current of air in the body of the receptacle and down through the seataperture, which flows through the pipe I and G into the draft-pipe.

lVhat I claim is- 1. In a dry closet such as described, the combination of a receptacle to hold the excrement, a draft-pipe connected to the said receptacle and opening into the body of the same and forming at the lower end a foot to receive and hold the lamp for creating the draft, and said lamp provided with a transparent guard to protect the flame and at the same time to allow for examination of the same, the said guard fitting against and forming part of the draft-pipe, substantially as described.

2. In a dry closet such as described, the combination of the receptacle A, the draftpipe H and H, connectingwires H the T connection between the draft-pipe and receptacle, and a heater for creating a current of air in the said receptacle and draft-pipe, substantially as described.

3. In a dry closet such as described, the combination of the receptacle A, a draft-pipe, a T connection between the draft-pipe and receptacle, a lamp at the lower end of the draftpipc, the diaphragm L, set in the draft-pipe below the junction of pipe leading from the receptacle, and a small pipe set in the said diaphragm and extending above the said junction, substantially as described.

In testimony whereof I have hereunto set my hand this 13th day of March, A. I). 1889.
